CATV Return Path Differential Amplifier
5 - 300 MHz
Features
21.2 dB Gain
5.0 V Bias
3.1 dB Noise Figure
External Bias Current Control

Description
The MAAM-011185 is a balanced GaAs MMIC
amplifier assembled in a lead-free 3 mm 16-lead
PQFN plastic package.
The amplifier is ideally suited for use in CATV return
path applications, including DOCSIS 3.1 systems: it
offers low distortion and low noise figure with high
gain. It typically provides 3.1 dB noise figure,
21.2 dB gain, and 30 dB MER up to 57 dBmV per
channel for 16-Channel 64 QAM signaling while
drawing 290 mA DC current @ 5 V bias.
